How to Set selected item in BottomNavigationView

Question

I am trying to set default item on activity created but it isn\'t working? This is my code:

protected void onCreate(Bundle savedInstanceState) {
    super.o         


        

Answer 1

There are two senario

Set the selected menu item ID. This behaves the same as tapping on an item.

Code example:

BottomNavigationView bottomNavigationView;
bottomNavigationView = (BottomNavigationView) findViewById(R.id.bottomNavigationView);
bottomNavigationView.setOnNavigationItemSelectedListener(myNavigationItemListener);
bottomNavigationView.setSelectedItemId(R.id.my_menu_item_id);

I you only need to check it without tapping

Code example:

  BottomNavigationView bottomNavigationView= (getActivity()).findViewById(R.id.bottom_navigation);
    bottomNavigationView.getMenu().findItem(R.id.action_manage_orders_id).setChecked(true);
